Hi Alexander,
This patch introduced a behavior change around GRO_DROP:
napi_skb_finish used to sometimes return GRO_DROP:
> -static gro_result_t napi_skb_finish(gro_result_t ret, struct sk_buff *skb)
> +static gro_result_t napi_skb_finish(struct napi_struct *napi,
> + struct sk_buff *skb,
> + gro_result_t ret)
> {
> switch (ret) {
> case GRO_NORMAL:
> - if (netif_receive_skb_internal(skb))
> - ret = GRO_DROP;
> + gro_normal_one(napi, skb);
>
But under your change, gro_normal_one and the various calls that makes
never propagates its return value, and so GRO_DROP is never returned to
the caller, even if something drops it.
Was this intentional? Or should I start looking into how to restore it?
Thanks,
Jason
